Abstract: A vertical mounting plate (47) supports on one side three split-shell cylindrical chambers (1,2,3) in plastic material with conducting external surface. Aligned horizontally and communicating internally via sealed band-joints (8), the shells are filled with pressurised e.g. SF6 gas. Shells are vertically divided, the halves (1',2',3') next the mounting plate containing isolating switches capable of connecting feeder cable terminations (15,32), traversing the plate, with busbars in the other half-shells (1'',2'',3''), or with earth. One shell (3) is backed by an insulated case (51) containing single-pole vacuum or SF6 circuit-breakers - opt., a fuse-cabinet - controlling local MV equipment, e.g. a transformer, with associated earthing switch (63). An outer cabinet (41,81,82,83), of metal plates cut, folded and riveted, supports the equipment and its LV ancillary gear.

Abstract: La présente invention décrit une tondeuse à gazon déchiqueteuse équipée d'une chambre de coupe fermée en mode déchiquetage, de sorte que les tontes de gazon restent à l'intérieur de ladite chambre sauf au moment où elles sont évacuées vers le bas par l'ouverture située au fond de la chambre. La chambre de coupe comprend une première partie de forme toroïdale qui, en général, entoure de près les extrémités de la lame. De plus, la partie avant de la chambre de coupe comprend un prolongement cunéiforme (48) s'avançant vers l'avant, dont les parois latérales (52) convergent pour former un triangle. Le prolongement cunéiforme (48) comprend également une paroi supérieure (50) qui se trouve entre les parois latérales. Cette paroi supérieure, dirigée vers l'avant de la tondeuse, s'étend en plan incliné vers le bas, de sorte que la hauteur du prolongement cunéiforme diminue progressivement jusqu'à atteindre un niveau 0 sur l'arête avant dudit prolongement. Le prolongement cunéiforme réduit la consommation d'énergie de la tondeuse lorsque celle-ci, en mode déchiquetage, est utilisée pour déchiqueter l'herbe.

Title: An ink jet recording head, an ink jet head cartridge, and an ink jet recording apparatus
Inventor: HIROSAWA TOSHIAKI
IPC: B41J2/175
Filed: 1997-07-30
Granted: 2005-05-24
Abstract: An ink jet recording head capable of separating or coupling ink tanks from or with the head comprises a recording device substrate having a plurality of recording devices thereon for discharging ink, a wiring device for giving electrical recording signals to the recording device substrate, an ink supply member for supplying ink to the recording device substrate, and a filter member for removing dust particles or the like in ink. This recording unit is provided with all the functions of discharging ink, and coupled with a holder member having only the function of holding and fixing ink tanks. With the structure thus arranged, it becomes unnecessary to connect ink supply paths as in the conventional art, hence eliminating the provision of sealing members. The number of parts is made smaller, while making it possible to carry out inspection of heads only in accordance with the recording units, which significantly contributes to simplifying manufacture and providing highly reliable heads at lower costs.

Title: Power conversion system for bi-directional conversion between hydraulic energy and electrical energy
Inventor: CARL UDO
IPC: H02J3/46
Filed: 1997-10-27
Granted: 2004-01-20
Abstract: A bi-directional power conversion system interconnects hydraulic and electrical power systems on-board a vehicle such as an aircraft, whereby the power conversion system can selectively convert available electrical power to needed hydraulic power or vice versa.  The power conversion system includes a hydraulic machine connected to the hydraulic system of the vehicle, an electrical machine connected to the electrical system of the vehicle through a power converter and control unit, a rotational drive shaft mechanically interconnecting the hydraulic machine and the electrical machine, and a priority and safety control unit that controls the operation of the system.   In a first operating mode,  for example in the event of a failure of a primary electrical generator, the hydraulic machine operates as a hydraulic motor driven by available hydraulic power from the hydraulic system to drive the electrical machine which operates as an electrical generator to provide electrical power into the electrical system. In a second operating mode, for example in the  event  of  a  failure  of  a  primary  hydraulic  pump,  the electrical machine operates  as an electric motor driven by electric power from the electrical system to drive the hydraulic machine operating as a hydraulic pump to provide hydraulic power into the hydraulic system.  A hydraulic valve arrangement and an electrical switch arrangement, as well as pressure and speed regulators are controlled by the control unit, and the system operation is monitored by sensors connected to the control unit, to activate the appropriate operating mode.

Title: Counterbalance mechanism for vertical opening door
Inventor: KRUPKE LEROY G
IPC: E05F1/14
Filed: 1998-01-12
Granted: 2001-06-05
Abstract: A counterbalance mechanism for a sectional garage door includes an elongated shaft mounted above the door opening and supporting spaced apart cable drums connected to respective cables which are connected at one end to the door for exerting a  counterbalance  force thereon.   Opposed torsion springs are connected to the cable drums at one end, respectively, and  to  respective  hub  members  which  are  axially slidable on but nonrotatable with respect to the shaft.  The cable drums are provided with detachable bushing members for engagement with the support brackets.  The shaft is connected to a non-reversible worm gear drive at one end.   The worm gear drive may be actuated to selectively vary the torsional deflection of the counterbalance springs by rotating the worm and a ring gear meshed therewith.  The worm gear drive may be detachably mounted on  one  or  the  other  of  shaft  support brackets  and a  lock plate  is  supported on the  shaft and engageable with a bracket to prevent rotation of the shaft when the drive mechanism is removed.  The door guide members are engaged with coil compression springs for centering the door between its guide tracks and to minimize skewing of the door during opening and closing movement.

Abstract: Mail pieces are produced by an apparatus which includes a printer, for printing a plurality of documents and envelopes in response to signals generated by a host computer under control of an application program. A mail finishing unit forms a plurality of mail pieces from the documents and the envelopes. A control unit controls the mail finishing unit to form an individual one of the plurality of mail pieces with individual attributes, or characteristics, such as envelope configuration, numbers of inserts, folds of the insert, and other characteristics. The attributes of any one mail piece may be different from attributes of others of the mail pieces, so that each mail piece may have individual attributes. The control unit receives the signals generated by the host computer; and is programmed to parse the signals from the host computer and to extract therefrom control signals generated under control of the application program. The control signals identify the individual attributes for the individual one of the plurality of mail pieces. The control unit responds to the extracted control signals by generating finishing control signals for the mail finishing unit to form the individual one of the plurality of mail pieces with the individual attributes. The control unit is further programmed to extract print signals for the print unit from the signals and to provide print control signals to the print unit responsively thereto. The application program may be a word processor, which outputs document pages for printing by the printer. A user may provide a particular format or protocol to a document page, preferably to the first page output by the word processor, which designates that page to the control unit as a control page including the various control signals. Upon recognizing the control page, the control unit extracts the same from the word processor output, so that the printer does not print, or attempt to print, the elements thereof as text.
